1. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport
Sammanfattning : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. LÄS MER
2. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport
Sammanfattning : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. LÄS MER
3. Biochemical Control Aspects in Lignin Polymerization
Sammanfattning : Lignins are produced by all vascular plants and they represent one of the most abundant groups of biopolymers in nature. Lignin chemistry research, which has been of great importance for the progress of pulping technologies, has been plagued by the difficulties of its isolation and characterization. LÄS MER
4. A paleolimnological perspective on liming – implications for defining reference conditions in Swedish lakes
Sammanfattning : Using paleolimnological techniques, I have studied surface-water acidification and the effects of liming in Swedish lakes on a decadal to millennial time-scale. The overall objective was to contribute to the discussion on the fulfilment of goals within the Swedish liming program. LÄS MER
5. Reproductive strategies and liming responses in forest field-layer flora
Sammanfattning : Liming increased species richness, in accordance with the species pool hypothesis, and number of plants of individual species in beech forest field-layer vegetation, by increasing establishment by seedlings and vegetative offspring. Turnover rates also increased, suggesting the explanatory value of the carousel model. LÄS MER
